Development Leadership

As the project lead and primary developer, I was responsible for:

Technical Leadership

• Architecture Design: Designed the complete system architecture and database schema
• Technology Selection: Chose optimal tech stack for scalability and maintainability
• Code Quality: Established coding standards and best practices
• Performance Optimization: Implemented caching, indexing, and optimization strategies

Project Management

• Requirement Analysis: Collaborated with Hack Club leadership to understand recruitment needs
• Timeline Management: Delivered the project on schedule for recruitment deadlines
• Team Coordination: Led development efforts and coordinated with stakeholders
• Quality Assurance: Ensured thorough testing and quality control before production deployment

Stakeholder Management

• User Experience Design: Designed intuitive interfaces based on user feedback
• Training & Documentation: Created comprehensive documentation and user guides
• Support & Maintenance: Ongoing support and feature enhancements
• Feedback Integration: Continuously improved the platform based on user feedback

Database Schema

The application uses the following main tables:

• profiles: User profiles with roles
• applications: Application submissions
• departments: Available departments
• recruiter_departments: Department assignments for recruiters
• application_settings: Global application settings

2. Install Dependencies

```bash npm install

or

yarn install ```

3. Environment Variables

Create a .env.local file in the root directory:

```env NEXT_PUBLIC_SUPABASE_URL=your_supabase_project_url NEXT_PUBLIC_SUPABASE_ANON_KEY=your_supabase_anon_key ```

4. Supabase Setup

1. Create a new project in Supabase
2. Get your project URL and anon key from the project settings
3. Run the database setup scripts in the following order:

-- Execute these scripts in your Supabase SQL editor
-- 1. Run the complete setup script
-- (Copy and paste the content from scripts/schema.sql)

-- 2. Run the email domain validation script
-- (Copy and paste the content from scripts/email_domain_validation.sql)

Important: The email domain validation script ensures only @vitstudent.ac.in emails can register new accounts. Admin accounts with @gmail.com emails created before this restriction will continue to work.

5. Run the Development Server

```

npm run dev
# or
yarn dev

Open http://localhost:3000 in your browser.
